Re: I have no luck

I think you're going to get a lot of flame for the Skar equipment. If it still works fine, I would probably run it until it goes, then have it repaired. Idk if that will cause more harm than good though. @ampjunkielikeme ;

Apollo Robb told me since the burnt fet is in the supply section it wont trip protect, but he recommends to fix it before more fets blow..

Re: I have no luck

Yeah, I was gonna say that it might damage other components in the process of burning. Hopefully since it is a small problem, the repair price would be cheap. Shoot, if it is only a fet, you could probably do the work yourself.

If its a burnt PS fet you really should have the power supply serviced man. I would start by replacing all of the power supply fets as they are all in parallel and all saw the same stress that caused the one to fail. Could have been one fluke bad part but I would not chance it. The power supply will be most reliable when all the fets are matched as closely as possible. Just throwing one new fet in to replace the burnt one is just a bandaid and not a very good one at that. You also will need to verify that all the gate resistors are still within tolerance. Power supply drivers and pwm IC need to be checked as well. Gate drive signal will need to be inspected on an oscope also. If it still works you may be lucky and all your power supply drive circuitry is intact. Could be lucky enough to have it be as simple as swapping fets or it could be a bit more involved. I wouldn't use it until you can have it serviced.

Well its being sent to Apollo Sound Products and hes known to do good work, well see what he does.
